钢箱梁拱桥模态分析及试验研究

Modal Analysis and Test Study for Steel Box Beam Arch Bridge

通过数值计算和试验的方法对钢箱梁拱桥进行了模态分析和试验研究,得到其计算振动频率和相对应的振型以及试验模态频率及振型,对计算模态和试验模态进行振型相关性分析,将数值计算的动态分析与试验数据有机地结合起来,验证了钢箱梁拱桥数值模型。

The calculated mode of steel box beam arch bridge was analyzed and its oscillating frequency and the corresponding mode were obtained from the numerical calculation.A correlative analysis of the oscillating frequencies and modes both from the numerical calculation and the experiments was carried out.The results from the correlative analysis proved that the dynamic analysis by the numerical calculation model of steel box beam arch bridge was available for practice use.
